The BBA-Plus solution is intended to enable cash handling departments with employee-operated cash machines - BBA - without necessitating the presence of at least two employees who have eye contact during business hours.This is made possible by biometric security applications which only enable disbursement from a BBA if two employees are present for the disbursement process. The biometric characteristics of the users are filed in the system and are compared with the user data detected by the biometric sensors to initiate a disbursement.
